All machines using nfsv3. Once a machine generate this error, the machine will NOT be usable. You cannot use the console, when you try to ssh, it will hang after you enter your password. The machine then needs a power cycled. Below is the log. May 8 10:45:41 duvel kernel: [347206.207773] BUG: soft lockup - CPU#0 stuck for 22s!
